Recruiting studies
- NCT07097480Recruiting
Study on virus spread from monkey bites to people
This study looks at whether viruses can be transmitted to people who have been bitten by a non-human primate (like a monkey). It aims to understand the risk and gather information that could help prevent infection.
ParisAges 18 years+ - NCT07422974Recruiting
Surgery results after pre-treatment for colorectal cancer
This study looks at how well patients recover from colorectal cancer surgery, comparing those who had chemotherapy or radiation before surgery to those who did not. The goal is to understand if pre-treatment affects surgical outcomes.
OsijekAges 18 years+ - NCT05940311Recruiting
Blood test for melanoma with BRAF V600E mutation
This trial studies a very sensitive blood test to detect melanoma-related genetic changes in people with BRAF V600E. It may help track the disease more closely and guide care in advanced or high-risk situations.
RomeAges 18 years+ - NCT04154553Recruiting
Genetic testing to prevent bad drug reactions or treatment failures
This study looks at whether a person’s genetic makeup can help choose safer medicines or improve how well treatment works. You may be asked for testing if you’ve had a bad reaction or treatment failure, or if you’re starting a new medicine that is known to be affected by genetics.
BaselAges 2 years+ - NCT04883502Recruiting
Testing a technique to rebuild bone lost after injury
This study looks at a surgical method that creates an “induced membrane” to help rebuild bone after traumatic injury. It may help people whose limb bones were damaged and are missing part of the bone.

Teeth bacteria study in seniors with and without Alzheimer’s
This study looks at the bacteria in the mouth (periodontal microbiota) to see whether they differ between seniors with Alzheimer’s disease and seniors without it. You may be asked for a sample from your gums/teeth and background health information.
Nice, CHU de NICEAges 18–90 - NCT05555693Recruiting
Brain chemistry study after surgery in older adults
This study looks at how brain “metabolomics” (small chemical signals in the brain/body) relate to thinking or mood problems that can happen after surgery in people age 65 and older. It may help doctors understand who is more likely to have these side effects after an operation.
Shanghai, Shanghai MunicipalityAges 65 years+ - NCT05885048Recruiting
Testing how cancer treatments affect future fertility
This study looks at how treatments that can harm ovaries or testicles (like certain chemotherapy, radiation, and immune therapies) may affect fertility. It may help you and others by measuring hormone levels (and in some cases sperm) before and during/after treatment.
BernAges 14–50 - NCT06111950Recruiting
Study of RNU4ATAC and RTTN gene conditions
This study looks at rare genetic syndromes caused by changes in the RNU4ATAC or RTTN genes. It aims to understand how these changes affect the body by studying patients, their parents, and fetal tissue.
BordeauxAges Any age - NCT06481813Recruiting
Lung Cancer Biobank Study for Newly Diagnosed Patients
This trial collects blood and tissue samples from people newly diagnosed with lung cancer (NSCLC or CPC) to study the disease over time. It helps researchers understand how different treatments affect the cancer and the body.
NantesAges 18 years+ - NCT05992272Recruiting
How cues affect drinking and smoking habits
This study looks at how certain cues (like seeing a drink or a cigarette) trigger cravings and behavior in people who drink alcohol or smoke. Understanding this may help improve addiction treatments.
BerlinAges 16–65 - NCT05088395Recruiting
Blood tests to track cancer signals after treatment
This study measures “circulating tumor markers,” meaning substances from cancer that can show up in blood, to better understand how cancer is doing after treatment. You may join if you recently received cancer care at a participating center and meet basic study and follow-up requirements.
ParisAges 18 years+ - NCT06842316Recruiting
Study on cannabis-like compounds for inflammatory arthritis
This trial tests whether plant-based compounds similar to cannabis (called phytocannabinoids) can help calm inflammation and improve immune function in people with certain types of arthritis or autoimmune diseases like lupus or Sjögren's disease. It aims to offer a new way to treat these conditions without the 'high' of marijuana.
OrléansAges 18 years+ - NCT07038733Recruiting
Lymph node study for kidney cancer patients
This study looks at lymph nodes in people with known or suspected kidney cancer to learn more about the disease. It may help researchers understand how kidney cancer affects the lymph system.
New Haven, ConnecticutAges 18 years+ - NCT07254338Recruiting
Blood chemicals study in lung scarring and high lung blood pressure
This study looks at special chemicals in the blood (metabolites) from people with both lung scarring and high lung blood pressure. It aims to learn how these chemicals change with or without treatment for the lung blood pressure.
Bron, RhoneAges 18 years+ - NCT02725060Enrolling by invitation
Study of autoimmune changes in postural tachycardia syndrome
This trial studies whether an autoimmune (immune system–related) process is involved in postural tachycardia syndrome (POTS), a condition where your heart rate rises when you stand. The study may help researchers understand what causes POTS and how it could be treated or monitored.
Oklahoma City, OklahomaAges 18–50 - NCT05854368Recruiting
Blood tests to detect early stomach changes and cancer
This study looks for a blood “signature” that can spot early, risky stomach changes (before cancer) and stomach cancer. It may help clinicians diagnose earlier and decide who needs closer follow-up.
Boulogne-BillancourtAges 18 years+ - NCT03958240Recruiting
Study how cancers trigger the immune system
This study looks at what makes some cancers more “noticeable” to the immune system. It may help researchers design better future immunotherapy by collecting information (often including blood samples) from people with different cancers.
ToulouseAges 18 years+ - NCT06054854Recruiting
Lung Cancer Biomarker Study (BIRD Biobank)
This study collects blood, tissue, and other samples from people with lung nodules, suspected lung cancer, or confirmed lung cancer to find better ways to diagnose and treat the disease. By joining, you help researchers discover new biomarkers that could improve care for future patients.
ToulouseAges 18 years+ - NCT06129253Recruiting
GLOBE-HPV: Study of HPV in communities

Common questions
- Are there clinical trials studying Blood samples?
- Yes. Clin2 currently lists 695 recruiting studies that include Blood samples, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Blood samples trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Blood samples an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Blood samples or a specific trial is right for you.
